The vids from Kung Fu Luong are excellent! The are some of the best that I've ever seen. They are designed so that people who have some background training can pick up the sets from the DVDs. Someone without any training would naturally have trouble, but my guess is that any YMAA people could learn from them easily.
Several of the DVDs are now available for purchase in English. The tai zu sets one and two are available, as is the xiao hong chuan. The tai zu set one is from the Han Qing-tan lineage and should be roughly the same set as the YMAA version. Perhaps some stylistic differences. The tai zu set 2 is from the mantis system through Wong Song-ting, and it's really good. The xiao hong quan is also through the mantis system and it's one of the hardest sets that Zhou laoshi teaches. You should be fairly well grounded in some solid training before attempting it.
Each DVD is quite long because each move is covered in detail. For example, xiao hong quan is three DVDs long and is 205 minutes in length. You will get your moneys worth from these DVD. I have all of them.
They are also multi-region. I haven't heard of any problems and people from all over the world buy them. If you experience difficulties, just email them.
